‘I still have a contract until 2016 at Chelsea and I think they’re happy about the way I’m developing.

‘They have the last word, so we shall see what’s happening next.’

Lukaku has scored 14 goals for the Toffees this term, following on from last season’s successful loan spell with West Brom where he netted 17 times and was nominated for the PFA Young Player of the Year award.
